Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to occasionally wavy with a coarse, uneven texture and a distinct oily feel. Some interlocked grain may be present in certain cuts.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It often shows dark streaks and has a duller luster due to high natural oil content.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Renowned for its exceptional resistance to rot, fungal decay, and termites due to high natural oil and silica content.
Common Uses
Ship and boat building (decking), outdoor furniture, high-end cabinetry, exterior construction, veneer, and turnery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown in plantations across tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Ranges from $30.00 to $50.00 per board foot depending on thickness, grain quality (FEQ), and whether it is old-growth or plantation-grown.
Wood Age Estimate
The visible oxidation and uniform honey-brown patina suggest a seasoned board, likely processed several years ago, though not antique (5-15 years).
Sustainability Status
Listed as Endangered on the IUCN Red List due to population declines in native forests. FSC-certified plantation teak is the most sustainable choice.
Workability
Generally easy to work but the high silica content has a significant dulling effect on cutting edges. Glues well only after surface oils are wiped with a solvent.
Notable Features
Distinctive leather-like scent when freshly cut. High oil and silica content make it one of the most weather-resistant woods in the world.
Finish Recommendations
Teak oil or Danish oil are preferred to enhance natural beauty. For outdoor use, it can be left unfinished to weather to a silver-grey patina.
Identification Confidence
High. The characteristic honey-brown color, straight coarse grain, and the visible oily surface texture are classic indicators of Tectona grandis.
